Definitions

  • the present invention relates to the field of tilting seating systems, such as sofas, armchairs or the likes.
  • the present invention relates to a device for the movement of resting components of a sofa, an armchair or the like.
  • the known devices used for this purpose comprise two or more electric motors.
  • Devices of this type equipped with more than two motors, each of which is dedicated to the movement of one of the resting components, that is to say the headrest, the back, the seat and the footrest, are also known.
  • the object of the present invention is to provide a device for the movement of resting components of a sofa, an armchair or the like, which makes it possible to overcome the disadvantages and drawbacks discussed with reference to the prior art and which is easy to produce, is economical, of reliable use and of reduced structural complexity.
  • a device for the movement of resting components of a sofa, an armchair or the like such as a headrest that is movable between a lowered position and a raised position, a back that is movable between a substantially erected configuration and a downwardly inclined configuration, a seat that is movable between a backward position and a forward position, and a footrest that is movable between a lowered, substantially vertical position and a raised position
  • said structure being characterised in that it comprises a telescopic member equipped with a movable portion controlled by a motor and able, jointly with further connection members, to place in reciprocal relation and to move said headrest, back, seat and footrest; said telescopic member being movable between three different configurations: a first configuration of minimal extension of the movable portion in which the footrest is in the lowered position, the seat is in the backward position, the back is in the substantially erected configuration and the headrest is in the lowered position; a second configuration of
  • FIG. 1 shows a sofa equipped with the device for the movement of resting components of a sofa, an armchair or the likes according to the present invention in the relative fully closed configuration, that is to say with the footrest retracted, the seat backward, the back substantially erected and the headrest lowered;
  • FIG. 2 shows the sofa from FIG. 1 , with the aforementioned device in its intermediate configuration, that is to say with the footrest retracted, the seat backward, the back substantially erected and the headrest raised;
  • FIG. 3 shows the sofa from FIGS. 2 and 3 , with the device in the fully open configuration, that is to say with the footrest raised, the seat advanced, the back downwardly inclined and the headrest raised.
  • 1 denotes a sofa as a whole, equipped with a movement device 2 for the movement of the resting components of said sofa 1 , such as a headrest 3 , a back 4 , a seat 5 and a footrest 6 .
  • a movement device 2 for the movement of the resting components of said sofa 1 , such as a headrest 3 , a back 4 , a seat 5 and a footrest 6 .
  • the movement device 2 comprises a telescopic member 7 equipped with a movable portion 7 A controlled by an electric motor—not illustrated for reasons of simplicity—and a relatively fixed portion 7 B able to rotate about a fulcrum 8 integral with the device 2 .
  • the movable portion 7 A is connected apically to a hinged apparatus 9 for the movement of the footrest 6 .
  • the movement device 2 also comprises, a seat kit 10 , connected to the telescopic member 7 and to the seat 5 and provided to bring forward and backward the seat 5 , and a back kit 11 , connected to the telescopic member 7 , to the seat 5 and to the back 4 , able to vary the inclination of the back 4 in relation to the seat 5 .
  • kits 10 , 11 both comprise respective pluralities of elements hinged to one another and moved by the action of the telescopic member 7 .
  • a hinged mechanism 12 fixed at two points both to the back 4 and to the headrest 3 and connected to the movable portion 7 A of the telescopic member 7 by means of a flexible element 13 equipped, at respective ends, with two connection joints 14 , 15 .
  • the hinged mechanism 12 is provided with a through-hole 16 having the function of guiding the movements of the flexible element 13 during operation of the movement device 2 .
  • the hinged apparatus 9 is fully retracted on itself, thus causing the footrest 6 to adopt a substantially vertical position adjacent to the seat 5 which is in turn in the backward configuration; the hinged mechanism 12 results also retracted, with the result that the headrest 3 is arranged substantially horizontally; whilst the back 4 comes to rest in a substantially erected configuration.
  • the subsequent ejection of the movable portion 7 A until the telescopic member 7 is maximally extended involves, simultaneously, lengthening of the hinged apparatus 9 and correspondingly raising of the footrest 6 , forwarding of the seat 5 by means of the seat kit 10 , and also inclining of the back 4 downwardly thanks to the operation of the back kit 11 .
  • the particular constructional characteristics of the movement device 2 allow the use of said device in sofas, armchairs or similar articles, having very diverse aesthetic characteristics, without any assembly constraint. Such articles equipped with the above-described device are further object of the invention.
